Bersicker is a fine name for a Norwegian wolf under the control of a malign influence. It brings to mind the Berserkers, Norse warriors who seemed to descend into a furious and mad frenzy when they fought - possibly as the result of psychological rituals or even drugs taken before battle. The Úlfhéðnar are of particular interest here, for their habit of wearing wolf skins in battle. The word berserker comes from the old Norwegian for bear-shirt.
